PROCESS FOR PREPARING OPTICALLY ACTIVE 1,3-BUTANEDIOL

Title:

PROCESS FOR PREPARING OPTICALLY ACTIVE 1,3-BUTANEDIOL

Document Type and Number:

WIPO Patent Application WO/1989/010410

Kind Code:

A1

Abstract:

An optically active 1,3-butanediol is prepared either by (1) treating a 1,3-butanediol enantiomer mixture with microorganisms capable of asymmetrically utilizing said mixture or a treated product thereof, or (2) treating 4-hydroxy-2-butanone with microorganisms capable of asymmetrically reducing it or a treated product thereof, and collecting the formed optically active 1,3-butanediol.
